At UofT we have a variety of specialized databases designed to help you find scholarly journal articles on your topic. In this list you will find databases addressing specific religious traditions (Index Islamicus or New Testament Abstracts) as well as databases casting a broader net (ProQuest Religion).
America: History and Life is one of our better resources for researching Native traditions.
In this list you will find databases addressing environmental issues from a variety of perspectives. Resources such as Environmental Sciences & Pollution Management will let you explore core environmental issues from many sides, and unique government document indexes such as Policy File and GreenFILE will help you get rare glimpes behind the scenes of environment-altering decisions.
Please keep in mind that interdisciplinary science databases like Scopus and Web of Science can help thorougly expose the science, but without delving into philosophical or spiritual implications.
Multidisciplinary databases will offer many perspectives. BAS will offer Asian insights on environmental or spiritual issues while IBSS will cover ethical and cultural ramifications. Please note that the first three databases on the list include the Native American perspective.
